Determine If an Error Has Occurred During Object Construction

This can be achieved in Java by throwing an exception from your constructor. Since constructors cannot return a value, this is the only way to perform error handling.

     Class MyCLass{
          private int x;
          File file;
         MyClass() throws MyException{
         x = 10;
         file = new File(“c:\\myFile.txt”);
         catch(Exception e)
          throw new MyException();
When you use this class, insert the code of the constructor in a try-catch block and catch the exception:

        MyClass mc = new MyClass();
    catch(MyException e)
       System.out.println(“Could not create an object of the class
